Why do Star Trek and Microsoft Have the Same Crappy Vision of the Future?

Among the host of bad design decisions is a scene where a woman is working on a tablet in her hotel room. When her daughter calls, it's not directed to the device she's already using. Instead, the woman has to pick up her "cell phone" (a smaller tablet) and use it as the videophone.

Marissa and I have been watching Deep Space 9 together, and I was struck by how similarly anachronistic all the information technology is. They hand USB sticks (sorry, "data crystals"?) around instead of using the network. Jake has a bundle of datapads instead of a single device containing all his textbooks and homework (or, better yet, carry nothing and access it from home and school consoles.) In a scene where Chief O'Brien has to accomplish some technological wizardry in the runabout, he goes to a special-purpose console in the back of the ship where he has to stand to work instead of reconfiguring one of the seated workstations. (Data managed to get nearly everything done from his station...)

Now, one of these dates from before the Internet, but what is Microsoft's excuse? Does anybody really think we are going to enter an era where devices are more specialized and specific functions are more tied to particular concrete objects?

(Also: "Sorry, we left your spiritual leader behind in the Gamma Quadrant; she can't leave the planet without dying. No, I'm sure you won't be able to go visit her. There are really tough defense satellites, see? Nothing we can do about that.")
